INDUCTION GENERATORS
The Commander 400 utilizes a brushless
Asynchronous Induction Generator to convert mechan-
ical energy into electrical energy. The following is a
brief description of an induction generator.
The induction generator is an induction motor driven
above the synchronous speed. The rotor conductors
pass through the magnetic field of the stator in a direc-
tion that converts mechanical energy into electrical
energy. Typical alternators (synchronous generators)
are not self-excited. An induction generator must be
connected in parallel with an electrical system that pro-
vides out-of-phase current or reactive power for excita-
tion. The capacitors used in the Commander 400 pro-
vide the same reactive power that an induction motor
would use for power factor correction. In fact, the
amount of reactive power used by an induction gener-
ator is equal to that used by an induction motor of the
same size.
To summarize, the stand-alone induction generator
used in the Commander 400 converts mechanical
energy into electrical energy. The electrical energy
supplied by the capacitors is transferred magnetically
to the rotor. Mechanical energy is supplied to the mag-
netized rotor in the form of torque and rotational speed.
The majority of this energy is magnetically delivered to
the stator weld coils.
